Ip-am valley, located at the eastern remote part of Korean peninsular was the place where a remarkable Confucian scholar Chang Hyon-gwang spent his secluded days. A large upright stone, called Ip-am, and undulating streams nearby were surrounded by mountains, which formed a large enclosed valley. After selecting 28 natural and artificial places, Chang named each of them. Chang compared the relationship between Ip-am and the 28 places with that of the Polestar and 28 Lunar Lodgings, which were known as the ancient Chinese astronomical concept. Also, Chang regarded the valley as a place where the Taoistic Deity could stay. Chang, who had deep knowledge of astronomy, wrote some books on it. It could be said that the comparison of his hermitages with the Polestar and the 28 Lunar Lodgings resulted from his deep passion for astronomy. He considered the Ip-am valley to be the core of the universe like the Polestar is the core of the celestial world. Some stars like the Polestar or the Dipper were regarded as the Deities of Taoism. We can find that Confucian scholars of the middle Choseon, like Chang Hyon-gwang, also tended to have some concern about Taoism.

The purpose of this study is that it is made clear the construction method of Japanese Castle Architecture in Korea as I study the construction method of Suncheon-Japanese Castle(順天倭城) in those days of Jeong-yu Japanese Invasion. Moreover, I intend to analyze the similarity and the difference between Suncheon-Japanese Castle and Korean Castle Architecture by a comparative study. The result of the study is showed that Suncheon-Japanese Castle seemed to be built with the object of a long time stay rather than it was of strategic importance for the national defense. In addition, it was different from other Japanese Castle in Korea because the watch tower(天守閣) of it stood in the middle of stronghold and the watch tower stronghold dividing the round of it while that of it stood the comer of stronghold. The face stone used in important part of watch tower, gate, and so on was mostly a trimed hexangular stone. On the other hand, the face abbuting on the Gulf of kwang-yang was made of naturally wild face stone. The stone cleared traces of Si-hyeol(矢穴) and domestic Castle in Japan was also made of this method after Im-Jin Japanese Invasion. According to the construction method, the wall of castle made use of the Netak(內托) method except the gate, the support stronghold and the watch. The early mountain castle in Korea have this construction method in common.

This study concerns especially Choryang-Weagwan which was the largest Japanese House left in Pusan through Chosun Dynasty. Choryang-Waegwan was known to have been jointly constructed by Korean and Japanese carpenters. Therefore, Weagwan was a place for exchange of architectural tradition (special features such as sliding door and straw mat) between Korean and Japan. Judging from this point of view, It is certain that mutual influences helped to shape architecture of Choryang-Weagwan. After establishment Choryang- Weagwan was gradually extended, owing to the prosperity of trade with Japan. But since late 18th century government of Chosun did not give as much care to maintaining Choryang- Weagwan as a result of deteriorating condition of commercial and diplomatic relations with Japan. From the beginning of Choryang- Weagwan construction, Superintendents of the construction were called Hun-do and Byl-cha, who acted as official interpreters as well. And, during construction works, they were called Gamdong-gwan, At the start of construction, Weagwan was built partly in Japanese-style by the carpenters from Tokugawa Shogunate. But as time passed, the participation rate of Japanese carpenters diminished gradually. After 1831, Japanese technician vanished extremely and repairing construction was continued by the Korean workers only.

This study reviewed the preservation status of the Early Western Style Architecture in Korea based on the on-site research of church buildings which are registered as National Cultural Properties. I have investigated 21 church buildings regarding the frequency, content and concept of restoration. The results are summarized as follows First, the churches have been restored extensively in every 17 years on the average. Second, the main restorations are replacement of bricks, painting, waterproofing, repair of roof and timber. And the main changes are extension of plan, removal of Interior posts, and replacement of floor. Third, the main concept of restorations are historical restoration(62%), critical restoration(23%), stylistic restoration(14%). Forth, the category of restoration have been changed, that is extending of incompletion (1st stage), functional improvement and extension of the span of life(2nd stage), improvement of facilities(3rd stage), restoration to the original state and conservation(4th stage). Fifth, the issues of repairing techniques are revival and replacement of weathered bricks, the removal of painting, and structural reinforcement. This study will be able to be used as the fundamental materials to improve the techniques of restoration of Early Western style masonry buildings.

The main purpose of this paper is to show that the new paradigm of a period can be constructed by the reinterpretation of the historical precedents or the dialectical mediation between the old and new. We can tell this process the creative dialogue between the past and present. The continuity and rupture, the renovation and succession of the tradition can be understand by this interpretive insight that opens the new horizon in architecture. In oder to prove this preconception this paper analyses the ideas and design principles of Le Corbusier. By showing how his main ideas and principles are formulated we can understand his unique position as a modernist and characteristics of his architecture. It is also the another purpose of this paper. This paper first looks into various aspects of his architecture and his personal background, then Investigates his unique approach to historical precedents. By the imaginative eye and comparison with inspiration he connected contemporary situation to the tradition and was able to deduce a new paradigm in architecture. His way of making relationship with the past was a priori, dialectical, and fundamentalistic. He always searched for universal norm, eternal rules, and timeless principles which are also modern and new. This both side shows well his characteristics and his architecture. Eventually he could invent a Modern language of architecture by the several ways of dialogue between the modem and the classical, new technology and old convention. We can say that his way of dialogue is a kind of reinterpretation of the historical precedents which enables open the future of architecture.

Jong Soung Kim is a rare architect in Korea who has consistently done research on the idea of the architectural technology for a long time. Therefore in order to understand Kimm's architecture, it is essential to examine his idea on the technology, which reveals the complicated relationship between divers architectural discourses. It is concerned with tectonics which was the most important theoretical movements in German architecture from the nineteenth century, the Mies van der Rohe's idea of the technology which provided the most powerful basis of modern architecture, Miesians' technological discourses which was at the height of prosperity in seventies in America, and High-tech architecture in eighties. Kimm's idea on the technology is defined as follow; 1) Kimm believe that although architecture begins in construction and materiality, it must culminate in artistic form. It's legacy of German tectonics. 2) He accepts Mies' three ideas on the technology. 'Architecture is the spatially apprehended will of the epoch.' 'Technology reveals the true nature of the will of the epoch.' 'We can attain a new beauty with the help of a new technology' 3) He takes a double attitude toward the idea on the technology of Mies followers. He accepts their architectural achievement according to technological progress, but criticize their technology-oriented attitude, deprived of spiritual enrichment. 4) Kimm's idea on the technology is distinguished from that of High-tech architect. The principal criteria exist in their different attitude toward the anonymity and the ethics of technology.
